Abstract

This paper presents a neuro-fuzzy approach for predicting vehicle fuel consumption. The prediction of fuel consumption of a vehicle has become a strategic issue. This is because it is not only related to the problem of the availability of fuel which is getting thinner but also the problem of the environmental impact caused. In this study, the acquisition of the car parameter data was inputted, namely the number of cylinders, displacement, horsepower, weight, acceleration, and model year. The output variable that will be predicted is fuel consumption in miles per gallon (MPG). 'Weight' and 'Year' are chosen as the two best input variables. Training results and predictions are expressed in the three-dimensional input-output surface graph of the best two-input ANFIS model for MPG prediction. The graph shows a nonlinear and monotonic surface, where MPG is predicted to increase with an increase in 'Weight' and a decrease in 'Year'. The results of the RMSE training were 2.767 and the RMSE examination was 2.996. Based on the results of the study showed that the greater the weight of motor vehicles, the greater the amount of fuel needed to travel the same distance.

Abstract

This paper presents performance analysis of synchronous generator: a case study in steam power plant PT POMI Paiton unit 7 Probolinggo, East Java, Indonesia. The steam power plant is the most powerful in Indonesia. The dominance of this type of power plant can be seen from statistical data that until the end of 2018 there were 48.43% of steam power plants out of the total installed capacity of national plants. Generators used in steam power plants are generally of the synchronous generator type, which in its operation always experiences dynamics from time to time as the load changes in electricity. In this study, an analysis of the performance of synchronous generators has been carried out concerning changes in electricity load. Synchronous generator performance analysis includes output voltage, active power, reactive power, power factor, and generator efficiency. The steam power plant in this study is the largest capacity power plant in Indonesia, thus providing an important role in the supply of electric power. Based on the results of the study, it has been shown that although the load dynamics that experience changes are very dynamic, the generator performance still has good performance.

Abstract

This paper discusses the analysis of the performance of an induction motor using the motor current signature analysis (MCSA) technique. Induction motor is a type of electric machine that is widely used in industry. One of the industries that utilize induction motors is a steam power plant (SPP). The role of induction motors is very vital in SPP operations. Therefore, it is necessary to monitor the performance, stability, and efficiency to anticipate disturbances that can cause damage or decrease the life of the induction motor. MCSA is a reliable technique that can be used to analyze damage to an induction motor. In this technique, the induction motor current signal is detected using a current transducer. The signal is then passed on to the signal conditioning and then into the data acquisition device. The important signal data is analyzed in adequate computer equipment. The results of this analysis determine the condition of the induction motor, whether it is normal or damaged. In this research, a case study was carried out at the Rembang steam power plant, Central Java, Indonesia. The results of the analysis of several induction motors show that most of them are in normal conditions and are still feasible to operate.

Abstract

This paper presents the performance of the electrical power distribution network under dynamic loading. The performance of a distribution system can be seen from the power losses generated by the network. If the power losses are low, then it can be said that network performance is excellent. Another parameter is the distribution network voltage profile. The voltage profile is significant in the distribution network. A very long distribution line will cause a voltage drop at the end of the network. This condition is very undesirable, so efforts must be made to improve the distribution network voltage profile. The method for correcting the voltage profile is by installing capacitors or reconfiguring the network. In this study, an evaluation of the performance of the distribution network at PLN Temanggung was conducted. The results showed that several network points experienced below-standard voltage drops. Therefore it is recommended to install power capacitors or reconfigure the networks.
